title: Endomyocardial biopsy diagnosis of small vessel disease: a clinicopathologic study.
abstract: We reviewed the clinical history of 191 patients undergoing endomyocardial biopsy and correlated signs and symptoms of heart disease with the presence or absence of small vessel disease. Idiopathic congestive heart failure (78%), arrhythmia (35%), and chest pain (25%) were the most frequent indications for biopsy. Small vessel disease was noted in 61% of the biopsies (67% female, 56% male): 10% severe, 36% moderate, and 15% mild small vessel disease. Patients with hypertension were twice as likely to have small vessel disease than those without hypertension. Of the 27 females with hypertension, 85% had small vessel disease, 67% with either severe or moderate small vessel disease. Small vessel disease was almost twice as frequent in patients with chest pain compared to patients without chest pain. Chest pain was significantly more common in patients with severe small vessel disease than in those with normal small vessels. Of all patients with chest pain, 18% had severe small vessel disease; however, of 20 patients with severe small vessel disease, 45% had chest pain. This analysis suggests that small vessel disease seen in endomyocardial biopsy is more common in women and is related to hypertension. When severe, it is likely to be associated with atypical chest pain.
